Android chrome bookmark results in mobile app usage automatically

I have noticed this happening on multiple websites whereby I bookmark a chrome web page on a website and when clicking on it on my Android phone it automatically opens up the mobile app for that website and navigates using it instead of the actual chrome mobile application on my phone. Have you guys changed the code here whereby that automatically happens for me? Because now this is happening for this forum . See attachments. The first shot shows that I have chrome bookmarks in a folder on my Android phone and the second shot shows the Excel help forum opening up automatically with their mobile apps instead of the chrome application. And I technically never downloaded this forums mobile application.
